Author Roger A. Wojtkiewicz uses the method of knotted spline variables (also known as piecewise linear regression) and a new method involving group spline variables to model nonlinearity in a variety of situations. Using spline variables to model nonlinearity allows researchers to specify unrestricted models for models that involve interval variables, allowing for greater flexibility in modeling any possible interaction.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781071950340\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9781071950340","offer_id":57949175742789,"sku":"9781071950340","price":50.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/01c7b3fe-64bd-4de4-a9f6-a9f036b713a4.jpg?v=1781755896","url":"https:\/\/shop.autorenwelt.de\/en\/products\/modeling-nonlinearity-and-interaction-in-regression-analysis-using-spline-variables-von-roger-a-wojtkiewicz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
